RAYMOND P. SI-IOLL, OF BARTONVILLE, ILLINOIS.

SELF-OILING CAR-AXLE.

SPECIFICATION forming part of Letters Patent No. 424,731, dated April 1,1890.

Application filed February 8, 1890. Serial No. 339,665. (No model.) i

To aZZ whom it may concern:

Be it known that I, RAYMoND P. SHoLL, a citizen of the United States,residing at Bartonville, in the county of 'Peoria and State of Illinois,have invented certain new and useful Improvements in Self-OilingCarAxles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in self-oiling car-axles.

The object of the invention is to furnish means whereby the constantoiling of the bearings may be overcome.

Reference may be had to the annexed drawings, making a part of thisspecification, in which like letters of reference refer to like parts,and in which- Figure l represents a plan view showing a part section ofmy device. Fig. 2 represents a side View of my invention, showing a boxor receptacle attached thereto. Fig. 3 is a sectional elevation of partof my invent-ion, showing an oil-receiving tube.

In the drawings, A represents a tube or pipe of the required length anddiameter, which is screw-threaded at either end and which is adapted toenter a threaded cavity formed in a casting C, as shown at Fig. l. Thiscasting C is made in one piece with the aXle D and plate B, Vwhichcarries, by means of bolts M M, Fig. 2, a box or receptacle L. A

receiving tube or conduit J, Figs. 2 and 3, is secured to the tube A bythe best means, and has formed in its interior a channel O, Fig. 3. Thisconduit .I is also provided with a setscrew K, which may be removed andreplaced at will through a hole in the iioor of the box.

or receptacle L.

In Figs. 1 and 2, Grepresents a channel bored longitudinally through theinterior and beneath the plate B of the casting O in a direction runningfrom the end of the tube or pipe A to end of the axle D. The channel Gcontinues in this direction until it reaches a point midway between theshoulder D and end of axle D, where it turns at right angles to thelength of the said channel G and terminates at a point E on theperiphery of said axle D.

The operation ot' my device is as follows: The set-screw K, Figs. 2 and3, is removed. The oil is poured in through channel O of the tube J andruns into the containing-tube A. Then tube A is half-lilled. The oilbeing on a level with channel G runs along said channel and dows out atthe opening E into the bearing parts of the Wheel.

The tube may be filled entirely up with oil, andby this means last manyweeks without replenishing or needing any care whatever.

This device is intended for use on miningcars, but may be used on allother vehicles as well.

That I claim as new, and desireto secure by Letters Patent, is

In a self-oiling axle, the combination of the containing-tube A in rigidconnection with the part composed of the casting C, axle D, and plate B,said casting having formed in its interior a channel G, as set forth anddescribed.

In testimony Whereof I aiiix my signature in presence of two witnesses.

RAYMOND P. SHOLL.
